Thanks for the info, I knew there was some reason I had dropped this
before.
Moritz, please tell Debian to also drop it so that I don't make this
mistake for the 3rd time sometime in the future...
thanks,

Sorry for the confusion! I've updated the Debian kernel security tracker
to drop the wrong commit reference.
The kernel in Debian unstable is using 4.6.1 now, so it no longer carries
backported patches for this bug.
Cheers,
